Electronegativity refers to the ability of an atom to attract shared electrons in a covalent bond. The higher the value of the electronegativity, the more strongly that element attracts the shared electrons.

Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element and lithium is the least.

Simple covalent compounds are generally named by using prefixes metal name + nonmetal name + suffix –ide to indicate how many atoms of each element are shown in the formula. Also, the ending of the last (most negative) element is changed to -ide. The prefixes used are mono-, di-, tri-, tetra-, penta-, hexa-, and so forth.

Archetypes were models of people, behaviors, or personalities. They were inborn tendencies that play a role in influencing human behavior.

For example: A hero, an innocent, the villain, the mentor, etc...

1. The mentor is a common archetype in literature. The mentor is usually old, and this person often has some kind of magical abilities or a much greater breadth of knowledge than others possess.

2. Characters representing the innocent archetype are often women or children. These character archetypes are pure in every way.

3. The villain wants to stop the hero archetype from achieving his or her goal. The villain is often evil, though there is often a reason—however warped that reason may be—why villains are so bad. Villains often want nothing more than to control and have power over everyone and everything around them.
